  margin:0 0 0 30px; /* A left margin to indent the list items and give the menu a sense of structure. */
  padding:0; /* Removes browser default padding applied to the list items. */
  list-style-type:none; /* Removes the bullet point that usually goes next to each item in a list. */
}

#containerul .symbols{ /* Various styles to position the symbols next to the items in the menu. */
  float:left;
  width:12px;
  height:1em;
  background-position:0 50%;
